ProcessHandle

Struct ProcessHandle 

Source
pub struct ProcessHandle { /* private fields */ }
Expand description

Handle for driving an interactive or non-interactive process.

This provides a unified interface for both PTY and pipe-based processes:

  • Write to stdin via writer_sender()
  • Read merged stdout/stderr via output_receiver()
  • Check exit status via has_exited() and exit_code()
  • Clean up via terminate()

Implementations§

Source§

impl ProcessHandle

Source

pub fn new( writer_tx: Sender<Vec<u8>>, output_tx: Sender<Vec<u8>>, initial_output_rx: Receiver<Vec<u8>>, killer: Box<dyn ChildTerminator>, reader_handle: JoinHandle<()>, reader_abort_handles: Vec<AbortHandle>, writer_handle: JoinHandle<()>, wait_handle: JoinHandle<()>, exit_status: Arc<AtomicBool>, exit_code: Arc<StdMutex<Option<i32>>>, pty_handles: Option<PtyHandles>, ) -> (Self, Receiver<Vec<u8>>)

Create a new process handle with all required components.

Source

pub fn writer_sender(&self) -> Sender<Vec<u8>>

Returns a channel sender for writing raw bytes to the child stdin.

§Example
let writer = handle.writer_sender();
writer.send(b"input\n".to_vec()).await?;
Source

pub fn output_receiver(&self) -> Receiver<Vec<u8>>

Returns a broadcast receiver that yields stdout/stderr chunks.

Multiple receivers can be created; each receives all output from the point of subscription.

Source

pub fn has_exited(&self) -> bool

True if the child process has exited.

Source

pub fn exit_code(&self) -> Option<i32>

Returns the exit code if the process has exited.

Source

pub fn terminate(&self)

Attempts to kill the child and abort helper tasks.

This is idempotent and safe to call multiple times.

Source

pub fn is_running(&self) -> bool

Check if the process is still running.

Source

pub async fn write( &self, bytes: impl Into<Vec<u8>>, ) -> Result<(), SendError<Vec<u8>>>

Send bytes to the process stdin.

Returns an error if the stdin channel is closed.

Source

pub fn is_writer_closed(&self) -> bool

Check if the writer channel is closed.
